Clinical Evaluation of Bulk-fill Restorative Materials

This study was a double-blind (evaluator and patient) randomized controlled clinical study with three study groups with an equal allocation. Three different restorative materials were compared in Class I, II, and V restorations.

The treated patients were called back for controls after one week, six months, and eighteen months. Restorations were evaluated clinically according to modified FDI criteria. In terms of marginal discoloration, fracture and retention, marginal adaptation, post-operative sensitivity, secondary caries, color match and difference criteria were examined.

Clinical evaluation was performed by one qualified clinicians using a mirror and probe under reflector light. Bite-wing radiographs were taken from the patients who were called for controls at 6-moth and 18-month to evaluate the formation of secondary caries.

Differences between adhesives at each time period were evaluated using Fisher's Exact test. The effect of time on restorations was evaluated using Wilcoxon Signed rank test (p < 0.05).
